	botanical.com - A Modern Herbal \| Groundsel - Herb Profile and Information
		Groundsel is one of those plants which follows civilized man wherever he settles, for there is hardly a European colony in the world in which it does not spring up upon the newly tilled land, the seeds probably having mingled with the grain which the European takes with him to the foreign country.
		Groundsel, so well known as a troublesome weed, is connected in the minds of most of us with caged birds, and probably few people are aware that it has any other use except as a favourite food for the canary.
		Groundsel is in flower all the year round and scatters an enormous amount of seed in its one season of growth, one plant if allowed to seed producing one million others in one year.

	Groundsel (Site not responding. Last check: 2007-10-22)
		Groundsel, or ragwort, common names for plants of genus Senecio, family Compositae or Asteraceae.
		The genus, one of the largest plant genera (1000-2000 species), occurs worldwide and is very diverse, including small trees, shrubs, annual and perennial herbaceous plants and succulents (ie, plants with fleshy tissues for conserving moisture).
		Exact species numbers are difficult to determine because of the hybridization and complex variation patterns found in some groundsels.

	Common Groundsel - An emerging Weed Problem in Low Desert Alfalfa - February 2004 - Yuma Farm Notes (ACIS) (Site not responding. Last check: 2007-10-22)
		Common Groundsel (Senecio vulgaris) is a difficult to control and potentially poisonous weed that has become established in LaPaz County and is becoming increasingly widespread.
		The proliferation of groundsel can also be correlated to the widespread use of the imadazlionone herbicides, Raptor and Pursuit, which are weak on this family of weeds.
		The preemergence treatments were applied on 10-29-03 when the alfalfa was 1-3” in height and the postemergence treatments were applied on 11-25-03 when the alfalfa was 4-12” in height and the groundsel was 1 leaf to 3 inch rosette.

	POST HARVEST GROUNDSEL CONTROL IN MINT, 1992
		Groundsel at the Gumwood Lane location was at the six to eight leaf stage, and at the Culver location groundsel was one to three inches high with flower buds.
		Although groundsel seed heads were collected from only one replication and therefore cannot be evaluated in statistically, seed viability did appear to be dramatically reduced as a result of herbicide application.
		Germination of groundsel seed in the untreated plot was 50 percent, and 4 to 10 percent for plots treated with Buctril alone or in combination with other herbicides.

		Riddell’s groundsel has stems that are somewhat less woody than those of threadleaf groundsel, which also tends to be more bush-like.
		Threadleaf groundsel typically grows in dry, gravelly, or hardpan soils, and may be found on plains and foothill areas; Riddell’s groundsel is generally found in slightly moister sites, along drains and especially in sandy places.
		Research results show that groundsels may be effectively controlled with 2,4-D (0.5 kg ai/Ac), picloram (0.5 kg ai/Ac), or a combination of 2,4-D and picloram (0.75 and 0.5 kg ai/Ac) when the plants are growing rapidly.

	Missoulian - Dog tooth groundsel ideal for a rock garden
		I prefer “dog tooth groundsel” - it's catchy, but while it is related to the Latin name of this plant (canus dog), it has no doglike features that I've been able to see, certainly no teeth, and I have never heard it bark.
		Young kids and willing adults learn easily to distinguish dog tooth groundsel from its similarly formed cushiony ilk, which include douglasia (known for its moss like leaves and hot pink flowers that bloom early in the spring), the succulent needlelike bitterroot leaves, and the elegant but hardy oval leaf buckwheat.
		While the individual dog tooth groundsel plants are charming, I think their special beauty comes from multiple plants blooming en masse in the rocky soil.
